There is another aspect to this. The dock at Stonedam in on conservation land owned by The Lakes Region Conservation Trust. The LRCT also owns Ragged Island.

The public access policy allows for many types of enjoyment but does not allow any overnight use.

Many members of this Forum are also LRCT members some making substantial contributions to allow LRCT to conserve land and/or to support maintenance. Some also volunteer time for annual clean up for places like Stonedam and Ragged.
If not for LRCT places like this would have been developed and there would be no public access period.
I find it offensive for someone violating the public access policy of these special places.
